"0 all whom it may concern:

Be it known that I, WILHELM C. BERLING, sui ject of the King of Sweden, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful improvements in Combination Magneto- Generators, of which the following is a specification.

This invention relates to a combination igniting and lighting magneto or electric generator designed more particularly for motor cycles.

Heretofore such machines have been equipped with separate magnetos mounted on independent supports and each having its own driving mechanism.

The object of my invention is to combine an igniting generator and a lighting generator in a single unit, thus simplifying thedevice and furnishing a compact, unitary structure which can be readily mounted in place of theordinary ignition magneto and driven from the same shaft.

In the accompanying drawings: Figure 1 is a central longitudinal section. of the improved magneto. Fig. 2 is an elevation of the front or driving end of the machine. Fig. 3 is a similar view omitting the front head of the casing and showing the lower armature shaft in cross section. Fig. 4 is an elevation of the rear end of the machine. Fig. 5 is a fragmentary top plan view there of. Fig. 6 is a fragmentary transverse sec tion on line 6-4"), Fig. 1.

Similar characters of reference indicate corresponding parts throughout the several views.

1 indicates the base of the machine upon which is rigidly mounted a frame or casing 52 which incloses the armatures 3 and L and associated parts of the igniting and lighting generators. This casing may be of any suitable construction. In the preferred construction. illustrated in the drawings, the armature 3 of the lighting generator is disposed directly above and parallel with the armature 4. of the ignition generator, and the walls of the casing follow the curvature of the armature, forming approximately cylindrical upper and lower portions, as best shown in Fig. 4. The ends of the casing are closed by removable heads 5 and 6.

As shown in Fig. 1, the armatures are journaled in suitable anti-friction hearings, in the upper and lower portions of the cas-,

ing. The ignition or high tension generator has a current interrupter 7 and a collector-- ring 8 of any suitable or conventional form, While the lighting generator has a suitable collector-ring 9.

As seen in Fig. 1, the upper and lower armatures are offset or vertically out of alinement. 10 indicates the permanent magnets of the lower armature and 11 the corresponding magnets of the upper armature. the two sets of magnets being reversely arranged to bring their poles opposite the coinpanion armatures. The legs of the magnets embrace the walls of the casing and bear against pole-pieccs 12 secured in openings in said walls, as shown in Fig. 6. Suitahie straps 13 and. 14 serve to securely hold the magnets in place.

The shaft of one of the armatures, preferably that of the ignition generator, is extended through the end of the casing and carries a driving gear or wheel 15 and also a second gear wheel 16 arranged within the casing and meshing with a pinion 17 mounted on the shaft of the upper armature 3. By this construction and arrangement the upper armature is driven directly from the lower armature, dispensing with a separate drive for the same.

To permit the lighting generator to be thrown out of gear during the day-time, the pinion 1.7 is preferably movable out of engagement with the gear Wheel 16. For this purpose, this pinion is mounted to slide endwise on the upper armature shaft and normally held in gear with the Wheel 16 by a spring 18 surrounding said shaft between the flanged hub 19 of the pinion and the opposing race-ring 20. lhe pinion is shifted out of gear with the wheel 16 by a slide 21 guided in a longitudinal groove 22 in the top of the casing and confined therein by a plate 53 secured to the casing. As shown in F ig. 1, this slide is provided in its underside with a fork 24v. which engages the flanged hub 19 of the pinion l7, and'in its upper side with a shifting pin or projection 25 which projects through a longitudinal slot 26 in the plate 23. Preferably combined with this pin and surrounding it is vertically-movable locking sleeve 27 adapted to interlock with one or the other of a pair of circular enlargements 28 at opposite ends of the slot 26. This sleeve is constantly urged downwardly on the pin 25 by a spring 29 which surrounds pin between a or shoulder 30 thereof and inturnedflange the base oi the sleeve. When the pinion ii is proper engagement with the gear Wheel 16, the spring-pressed sleeve is seated in the outer enlargement 28, as shown in t drai gs, positively locking the pinion in that position. To shift the pinion out of gear said sleeve is Withdrawn from said enlargement and the slide 21 is pushed rearivardly by nieansmf the sleeve until the latter snaps into the rear enlarge ment 28, thereby locking the pinion in its inoperative position.

This improved combination igniting and lighting magneto aliords a number of important advantages. As both generators are combined in a single compact unit, the de vice can be mounted on a motor cycle on the same bracket or support as the ordinary high-tension magneto and driven from the same shaft. This enables manufacturers of motor cycles to adopt or substitute this im proved magneto for the ordinary separate magnetos Without requiring any change,- rearrangement or re-construction of the parts of their machines. This unitary construction is moreover lighter and less expensive than two separate magnetos and requires the manufacturer to keep only one kind on hand, instead of tWo. The combination of the two generators in such manner that one is driven from the other also simplifies the construction and reduces the cost oi -the driving mechanism as Well as facili tates the installation of the device.

claim as my invention:

A combination magneto, comprising a singieframe'or support, an igniting orator and a lighting generator both mounted in said frani'ie, and means for driving the lighting generator from the igniting generdriving means including members ear with each shaft, and means for driving the last-named I shaft.

3. A single frame or support, an igniting generator and a lighting generator both mounted in said frame, the rotary armatures of said generators being arranged one above the other and ofiset laterally, reversely arranged permanent magnets arranged side by side and associated with the respective armatures, and means for driving one of said armatures from the other.
